two audio tracks with the same sounds

Hello,

I record videos by two video cameras.

I use two mics to record audio. Both mics records good sound.

I mostly use these two audio tracks for synchronisation.

Should I use these both audio tracks recorded by two mics or I should choose the better sound and use only one audio track in the final video?
What is the proper approach for using audio in the videos?

Do you use such two audio tracks with the same sounds only for making synch?

I mean such audio tracks which have very smiliar quality and are recorded indoors.

How do you do with it?

Regards

Marcin

I am 42. I have been creating videos since 2009 (the date when my first daughter was born in). My first video software was Pinnacle, next one was Sony Vegas 8 (I am not sure if remember it correctly). I am also a developer and wedding movie operator and editor. For example: I have created an Android app which let me control Vegas Pro rendering progress level on Android smartphone. I created it for fun, because I also love programming. I also created my own plugin for Audio To Text feature specified usage from Vegas Pro 19. I created proxy creation plugin which uses multiple GPU threads (maximum 3) to create proxy files for Vegas Pro. I also written many others plugin/softwares which enhance my video editing, also wedding editing.

It depends... If all the audio came from the same source (a cam-hop or mixing console feed for instance) just use one. If they are from different mic placements .. or one from the a house console and the other from room mics, you can mix them together to whatever sounds good. Of course, in that scenario, attention must be paid to mono compatibility and other phase issues.

If changes in the camera shot has some significance, then you would want the audio to match (such as an interview or dramatic scene) but if audio and shot change does not have any affect on the content, you would want to use the best audio.
